Consider a computer system with DMA support. The DMA module is transferring a 1-byte character in one CPU cycle from a device to memory through cycle stealing at regular intervals. Consider a 4 MegaHertz processor. If 1% processor cycles are used for DMA, then the data transfer rate of the device is bytes per second.
